IMPROVEMENT IN SHUTTLE FOR LOOMS.

Specification forming part of Letters Patent No. 43,152, dated June 2l, 1864.

To all whom it may concer-n:

Be it known that I, AUGUSTUS D. CLARK, of Wilkinsonville, in the county of Vorcester and State of Massachusetts, have invented a new and useful or Improved Shuttle for Looms 5 and I do hereby declare the following to be a full and eXact description of the same, reference being had to the accompanying drawings, making part of this specification.

Of the said drawings, Figure l denotes a central vertical and longitudinal section of a shuttle as constructed in accordance with my invention, the same exhibiting its spindle and bobbin as in their proper operative positions. Fig. 2 is a similar section representing the spindle as raised to its highest position in order to enable the bobbin to be either removed from or applied to the spindle. Fig. 3 is an under side view of part of the shuttle.

The nature of my invention consists in an improved shuttle having its several parts i constructed, arranged, and applied together in manner and so as to operate as hereinafter set forth.

In the said drawings, A denotes the body of the shuttle as constructed of wood, and having each of its ends provided with a metallic conical head or cap, B, in the ordinary manner. The said shuttle is formed with a bobbinchamber or space for reception of the bobbin G.

, G is the spindle, which has a head, D, ot' l the form in longitudinal section as shown in the drawings.

a is a fulcrum or pin disposed transversely across one head of the shuttle, upon which the spindle C turns. The said head D is formed with a iiat face or bearingsurfaee, o, to act in conjunction with the spring or retainer E, for the purpose of holding the spindle iirml y in its place while the shuttle may be performing its function in the process of weaving. The rearlower part of the said head D is formed with an angular shoulder or incline, b, the same constituting a bea-ring or estopper to the spindle when it has been raised sufficiently high to enable the bobbin to be either applied to or removed from the spindle. The said retainer consists of a short, flat, slightly-curved spring, which is arranged in a chamber, f, (formed in one head of the shuttle,) and is confined therein by means of a screw, c, (shown in the drawings,) passing through its rear end. By this peculiar construction of the head of the spindle-viz., with the flat bearing-surface o, and forming the retainer with a corresponding iiat surface to rest upon the said flat face of the head-we have a sure means of holding the spindle in its proper place when the shuttle may be in use, and which will also allow the spindle to be elevated and depressed whenever it may be necessary.

F is a spring-catch, which is arranged flatwise underneath the retainer E and in the said chamber f, and is fastened to the shuttle by the same screw or device whichconnes the retainerin its place. The said springcatch consists of a iiat piece of metal bent at its upper end at or about a right angle with the main part, so as to form a short lip or catch, s, which is to enter an annular groove formedin the head .f of the bobbin, and thereby serve to confine the bobbin in its proper place when the shuttle may bein opcration,the same being as shown in Fig. l.

By my peculiar construction and arrangement of parts the retainer and spring-catch operate independently of each other, the retainer holding the spindle in place when the shuttle is in use, while it also allows the spindle to be moved upward in order either to remove a bobbin from the spindle or apply one thereto, as maybe desirable. The springcatch F is so formed and arranged as to operate independently of the retainer and be capable of adapting itself to heads of differcnt diameters, the object of the said springcatch being to hold the bobbin in place in the shuttle. While each performs its proper function in holding the spindle or bobbin in its proper position when the shuttle is in operation, still they are so combined or arranged that by depressing the head of the spindle the retainer will be forced downward and against the spring of the catch s, and will force it out of its groove in the head of the bobbin, and thereby allow the bobbin to be withdrawn from the spindle and the shuttle whenever it may be necessary.

From the above it will be seen that my improved shuttle is not only very simple in construction and effective in operation, but by its peculiar arrangement of parts it is not liable to get out of order.

I do not claim providing a shuttle with a My improved shuttle, having its spindlespring-eateh so arranged that the bobbin may head D,its spring'eateh F, and spring-retainer be either applied to its spindleor removed E,constructed,arrangechand applied together therefrom hya singlemovementof the spindle. in manner and so as to operate as set forth.

Nor do I claim any of the devices as shown in AUGUSTUS D. CLARK v Patent No. 12,780 for holding the spindle in its proper position While the shuttle may be Witnesses:

in use; but, S. W. LELAND,

That I do claim as my invention is" HORACE LELAND.
